Leners Patent No. 89,090, dated Apta 20,1869.

IMPROVED GASHOLDER To all whom tt 'may concer/u Be it known that I, CHARLES A. STEBBrNs, of Springfield, Hampden county, State of Massachusetts, have invented a new and useful Improvement in Gas- Machines; and I do hereby declare that the following is a full and clear description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

In the drawings, the iigure' shows the sectional view vertically through a gasometer, such as is used in the gas-machine patented by M. O. Stebbins,r October 27, 1868, land it is to this class of machine my improvements more particularly relate. Y

The object of my improvement is to prevent the escape of odor from the gas-receiver. This odorv comes usually from the water in the tank, perm eating through the joints between the tank and the cover.

In my improved gasometer the main body of water is kept pure, no gas being conducted beneath its top surface at any part. I construct, however, a smaller and inner tank, C, which contains suiiicient water to purify the gas, and which has no communication with the water surrounding it in the tank B, or outer one, the tank C rising sufficiently high above the surface of the i'vater around it to prevent its contents from splashing over into the main tank.

Ordinarily the pipe a, conducting the newly-formed gas into the receiver, permitted the gas to escape under the surface of the water in the tank B, and to bubble up through it. This impregnated it with its peculiar odor, which, as before stated, escaped somewhat through the imperceptible space between the sides of the tank and the cover A, at c.

In my device, the gas is conducted from the pipe a underneath the surface of the water in the tank C, and it bubbles np into the receiver without communicating with the water in B at all, except so far as it rests upon the top surface of the latter.

By this means the water in the tank B is kept pure, and free from odor, while that in O serves to' cleanse the gas from impurity.

In the drawings it is shown that both pipes, the one a conveying gas into the receiver, and the one bconveying it out from the same, pass through the bottom of the innertamk C, and have no connection with the main tank B.

The advantage of this improvement is that the machine is rendered inodorous, bythe impure water being entirely cut ofi` from contiguity With the joint at c.

Now, having described my invention,

What I claim as new, and desire to secure by Iletters Patent, is

l. The construction of a gasometer, in such a manner that an inner body of water serves for purifying'the gas before reaching the receiver, said inner body of water being kept from contact with the outer body of water forming the filling for the main tank, which illing remains pure, substantially as shown.

2. The arrangement of the tank C, pipes a and b,

tank B, and cover A, substantially in the manner and for the purpose herein set forth.
